"Please be aware of likely tricky road travel conditions," added the Met statement, with the warning in place until 9am on Tuesday.

The Met's chief forecaster said: "With little cloud and light winds, fog is expected to readily develop during Monday evening, affecting the evening rush-hour in some areas as well as the morning rush-hour on Tuesday.

"Fog is then expected to be locally slow to lift and clear on Tuesday, lingering for much of the morning and perhaps onwards into the afternoon in some spots."

The Met Office also took to Twitter to warn cyclists about the conditions and alert motorists they will be less visible as the fog develops.

Fog, however, may well prevent frost and cars icing up said the Met Office, with a minimum temperature of -1C forecast.

And after a chilly fortnight, milder temperatures will return by the end of the week, with the mercury potentially tipping 13C to 15C.

The Met Office said the jet stream will bring changes to weather this week, feeling less cold mid-week and forecasting milder air coming up from the south west - this milder air will bring temperatures in the mid-teens.
